Prevalence of methylenetetrahydrofolate reductase C677T polymorphism in eastern Uttar Pradesh

AIM: This study was aimed to evaluate the 5, 10-methylenetetrahydrofolate reductase (MTHFR) C677T mutation in eastern Uttar Pradesh population. MATERIALS AND METHODS: Polymerase chain reaction (PCR) using specific primers followed by amplicon digestion by Hinf I restriction enzyme was used for MTHFR C677T polymorphism analysis. Total 250 subjects were analyzed. RESULTS: The CC genotype was found in 192 subjects, followed by CT in 56 subjects and TT in 2 subject. Genotype frequencies of CC, CT and TT were 0.768, 0.224 and 0.008, respectively. The frequency of C allele was found to be 0.88 and that of T allele was 0.12. CONCLUSION: It is evident from the results of the present study that the percentage of homozygous genotype (CC) is highest in the target population.
